has anyone ever run wires from the blinker light in the ecu that shows what code your throwing to a light in the dash?

would it be as simple as just opening up the ecu and running wires from the 2 prongs on the light?

would be a lot easier to see what code your throwing if you are throwing one than to undo the carpet.

You throw codes that much????

 

every so often i throw a code, always the same one, i beleave its just a loose wire, but i use to run a dif. code that was more serious and i just always have to make sure its not the other code.

doing a turbo set up soon, so its not unlikely for me to throw a code or 2 at first, before i have it perfect, it would just make it easier.

 

One of the reasons why I hate OBD0.

 

whats wrong with obd0?

 

since i got no helpfull responce ill bump...

and would it be as easy as running prongs from the lights in the ecu?

Pretty much. Although I would probably buffer it with a unity gain opamp so you dont place additional load on the ecu circuitry. Then run the output of the opamp to an LED. Piece of cake.

If you wanted to get really fancy you could use a photodiode,phototransistor, or photoresistor to detect the light so you would never have to open the ecu or even touch the circuitry of the ecu.

 

lol... i like your thinking...

would probably be easier to use a relay though...

that whole post confused me...

if your not being sarcastic than thanks... what do you mean by running a relay?

A relay is a dumb idea. A typical relay pulls a few hundred milliamps far more then just adding an LED.

Your problem is you dont know how much of a load your circuit can supply. Overload it and you fry it. You connect something it may/ may not work or may just fry over time which is more likely to happen.

Adding what I suggested you take no risk in frying anything because the load a unity gain opamp places on the circuit in almost 0.

If you dont know what you are doing then I suggest you find someone who does or have a spare ECU ready.

 

i have 2 spare ecu's that always throw codes... ill test the idea out on them before i do it on my main one
